SEAM- FOR SEWED ARTICLES.

T o all whom f vmg/ concern:

Be it known that I, SAMUEL GEORGE TATE, a citizen of the United States, residing at Chicago, `in the county of Cook, State of Illinois, have invented certain vnew and useful Improvements in 4Seams for Sewed Articles, of whiohthe following' is aidescription, reference being had to the accompanying drawing and to the figures of l0 reference marked thereon.

The' invention relates to new and useful..

improvements in seams for sewed articles, and more particularly to what is known in the art as a covering seam which may be used for joining fabric sections to form a flat seam, or which may be used for ornamenting the fab-ric. An object of the invention-is to provide a flat seam consisting of a plurality of needle threads having the loops of the needle threads locked and secured by a single looper thread, and wherein said looper thread is secured by two of the needle thread loops so as to prevent the seam from ravel- 225 ing, and wherein one strand of the looper thread is carried laterally about another needle thread loop so as to aid in covering the edge of the fabric.

In the drawings which show by way of 3o illustration one embodiment of the inventionz Figure 1 is a top plan view on an enlarged scale showing a seam embodying my improvements Fig. 2 is a bottom and Fig. 3 is an enlarged view of the looper thread alone laid as it appears in the seam. As illustrated in the dra-wings, I have shown my invention embodied in a seam for uniting two overlapped fabric sections A and B. The needle thread 1 is formed into a series of needle thread loops 2, which are arranged in a row and which pass through the fabric section A, only, said needle thread loops being located adjacent to the edge of the fabric section B. A second needle thread 3 is formed into a series of loops 4 which pass through the fabric section B only, and said thread loop-s are in a row adjacent to and parallel to Jthe edge of the fabric section A. A third needle thread 5 is formed into a series of loops 6, which pass through both of the 35 plan view of the same,

fabric sections A and B and serve to unite the same.r The needle thread loops in all the rows are connected on one face of the fabric by a cross thread 7 which is laid about one loop in one outside row of needle thread loops, and then about one loop in the other outside row of needle thread loops each needle thread loop in the outside rows beingengaged by the cross thread. particular'laying per se of the cross thread shown inV the drawings and 'referred to` above, formsno part of the present invention, and any other arrangement of cross thread or threads may be used, the essential feature being the use of a cross thread which joins the outside rows of needle thread loops, and which is tied down by a central needle thread.

0n the other face of the fabric from the cross thread, the needle thread loops are locked and secured by a looper thread 8. Said looper thread is formed into a series of loops 9, and each loop is passed through first a needle thread loop 2, then a needle thread loop 6, and then a needle thread loop 4. The bight of the looper thread loop 9 is enlarged and extends about the next two needle thread loops 2 and 6 which are entered by the next looper thread loop.

In the making of the seam, this enlarged end of the looper thread loop is held open, so that the two needles forming the needle thread loops 2 and 6 will enter the same. The strand l0 of the looper thread loop 9 is also carried laterally and extends about the needle thread loop 4. The invention hinges particularly about the securing of the looper thread loop so as to prevent the seam from raveling. By the enlargement of the bight of the looper thread loop as described above, there is a sufficient length of looper thread loop so that should any attempt be made to ravel the same, these looper thread loops will engage the fibers of the body' fabric and become entangled, and any strain on the seam when the thread is broken will be insullicient to pull the enlarged end of the looper thread loop through the needle thread loop' and cause the raveling of the seam.

While my improved seam is particularly adapted for joining lapped fabric sections to form a flat seam, it is also very useful for ornamental purposes.

This

thread being formed into loops, each of' which extends through a needle thread loop in each row, the bight of the looper thread loop being enlarged and extending about the needle thread loops in two of the rows entered by the next formed looper threadV loop, and one strand of the looperv thread loop being extended laterally and about the needle thread loop in the remain-` 2. A covering seam for sewed articles comprising overlappedf fabric sections, a row of needle thread loops passing through one section adjacent the edge of the other section, a second row of needle thread loops passing through the second-named fabric section and adjacent the edge of the firstnamed section, a third central row of needle thread loops passing through the `overlapped sections, a cross )thread extendingA about each needle thread loop in the outer rows and tied by the needle thread of the central row of needle thread loops, and a looper thread joining said loops on the other face of the fabric, said looper thread being formed into loops,each of which extends through a` needlepthread loop'in eachv row, the bight ol the'looper thread loop being enlarged and yextending about the needle thread loopsV in two of the rows entered by the next formed looper thread loop, and one strand of the looper thread loop b'eingextended laterally and about the needle thread loop in the remaining row.
